Controller not connecting to the Cortex

Hello my name is Payton and I am having trouble trying to connect my controller to the cortex. I have downloaded the firmware to both the cortex and controller, hit the config button on the cortex, changed the cortex, keys, and the remote, and also established a vex link on everything, but when I try to connect the controller and the cortex with keys it would not connect. There would be a green light on the joystick icon and also on the controller a yellow light would flash rapidly on VEXnet on the cortex two yellow lights would flash rapidly on VEXnet and Game and a green light would flash slowly on robot.

#pragma config(Motor,  port2,           LFDriveM,      tmotorVex393, openLoop)
#pragma config(Motor,  port3,           LRDriveM,      tmotorVex393, openLoop)
#pragma config(Motor,  port8,           RRDriveM,      tmotorVex393, openLoop, reversed)
#pragma config(Motor,  port9,           RFDriveM,      tmotorVex393, openLoop, reversed)

#pragma userControlDuration(120)

#include "Vex_Competition_Includes.c"   //Main competition background code...do not modify!

task usercontrol()
{
	// User control code here, inside the loop

	while (true)
	{
	  motor[LFDriveM] = vexRT[Ch3];
	  motor[LRDriveM] = vexRT[Ch3];
	  motor[RFDriveM] = vexRT[Ch2];
	  motor[RRDriveM] = vexRT[Ch2];
	}
}

Here is my code, I do not see anything obviously wrong with it but if any one could help that would be great.

Thank you,
Payton

Your code should not affect getting a Link - displayed by a fast flashing Green VEXnet LED on both the Joystick and the Cortex when VEXnet Keys are installed on both.

The fast flashing Yellow VEXnet LED on both the Cortex and Joystick is normal when both units are in Search Mode - looking for their “mate”.

Do both the Cortex and Joystick display the same ID number when connected to the PC and using the VEXnet Upgrade Tool? If not, connect the Cortex to the Joystick using a USB A-A Cable, now Turn ON only the Cortex, wait for a Green VEXnet LED on both the Cortex and Joystick. Now Turn OFF the Cortex, remove the A-A Cable, install VEXnet Keys into both units and Turn both ON.
